If X is a vector or a matrix, erfinv(X) computes the inverse error function of each element of X.ExamplesInverse Error Function for Floating-Point and Symbolic Numbers Depending on its arguments, erfinv There are several approximations of this form each of which reaches a little further into the tail of the erfc function (at long double precision the extended exponent range have a peek here

The th coefficient of this series can be computed as (17) where is given by the recurrence equation (18) with initial condition . The Maclaurin series of is given by (15) (OEIS A002067 and A007019). However, it can be extended to the disk |z| < 1 of the complex plane, using the Maclaurin series erf − 1 ( z ) = ∑ k = 0 Perl: erf (for real arguments, using Cody's algorithm[20]) is implemented in the Perl module Math::SpecFun Python: Included since version 2.7 as math.erf() and math.erfc() for real arguments.

New York: Dover, 1972. Ch.5 in Combinatorial Species and Tree-Like Structures. Java: Apache commons-math[19] provides implementations of erf and erfc for real arguments. Despite the name "imaginary error function", erfi ( x ) {\displaystyle \operatorname 8 (x)} is real when x is real.

Definite integrals are given by (11) (12) (13) (14) (OEIS A087197 and A114864), where is the Euler-Mascheroni constant and is the natural logarithm of 2. PARI/GP: provides erfc for real and complex arguments, via tanh-sinh quadrature plus special cases. Negative integer values of Im(ƒ) are shown with thick red lines.

Accuracy checks using high-precision test values. Inverse Error Function Excel The inverse complementary error function is defined as erfc − 1 ( 1 − z ) = erf − 1 ( z ) . {\displaystyle \operatorname ζ 8 ^{-1}(1-z)=\operatorname Press, William H.; Teukolsky, Saul A.; Vetterling, William T.; Flannery, Brian P.
